Privacy

1. Practice data stays on the device

Practice answers, progress, statistics, daily goals, reminder preferences, and solfège settings are stored locally on the device in ChangMing 1.0. They are not currently uploaded to a ChangMing server or synchronized between devices.

2. Optional Kynoray account

You may use ChangMing without signing in. If you choose to sign in, ChangMing uses the shared Kynoray account service. That service may process your Kynoray user identifier, name, email address, profile image, chosen sign-in method, and security records as described in the Kynoray Privacy Policy.

Signing in does not currently upload your local practice history.

3. Notifications

If you enable practice reminders, ChangMing schedules a local notification based on your unfinished daily goal. You can disable reminders in ChangMing or in system settings.

4. Advertising, tracking, and AI training

ChangMing does not contain advertising and does not track you across apps or websites. Kynoray does not sell ChangMing or Kynoray account information or use it to train artificial-intelligence models.

5. Clearing data and deleting an account

Removing ChangMing or clearing its local data removes practice information stored on that device, subject to the device platform's backup behavior. This does not delete a shared Kynoray account.

To manage or delete the shared account, visit Kynoray Account Security. Account deletion can affect access to other Kynoray products.
